| With the rapid development of today’s society,the degree of aging in China is deepening.At present,the parents of the first batch of one-child families in country have also entered the old age,and the society is facing the contradiction between pension willingness and scarcity of pension resources.In recent years,with the vigorous development of computer technology and Internet of things technology,it has become a trend to combine the elderly care problem with intelligence.This paper takes the Internet of Things and cloud service technology as the starting point to construct a Wi Fi + Zig Bee + cloud platform home care system for elderiy.At present,most intelligent pension care devices can only monitor a certain type of data.This article combines the living needs of the elderly,and the design can simultaneously collect multiple physiological signals,activity records,and indoor environmental parameters.Understand the architecture of the Internet of things,design the main control unit networking to control other data acquisition equipment,and select Zig Bee wireless transmission technology with low power consumption and flexible networking.GSM remote communication technology is used to send SMS to the guardian to realize real-time alarm in case of abnormal data or emergency call for help from the elderly,which solves the problem that the guardian cannot receive messages at the first time due to the single communication mode.The environment and medication monitoring unit is designed to be attached to the medicine box to monitor the elderly’s living environment and daily medication data.The physical sign monitoring unit is designed to carry on the elderly,collect the heart rate and body temperature of the elderly and send them to the main control unit.The activity monitoring unit is designed to be placed on the toilet door to record the daily night data of the elderly.The main control unit uses the esp8266 module as the intelligent gateway to connect the device with the cloud platform based on mqtt protocol to upload data to the Internet in real time.One NET View3.0application interface is used for visual development to achieve data interaction.Finally,this paper uses support vector machine algorithm to identify the possible negative emotions of the elderly,so as to monitor both physical and mental health.After testing,the system can effectively monitor various information,timely alarm in case of abnormalities,and upload data to the cloud platform in real time.The elderly and their guardians can view all the data of the elderly anytime and anywhere.The equipment has a long standby time,which has a certain use value for the elderly who can take care of themselves at home. |
